Description

【０００１】
【発明の属する技術分野】
本発明は、入水圧が設定値以上になると開放して便器開口部に通水するリリーフ機能を備えた人体の局部を洗浄する衛生洗浄装置に関するものである。
【０００２】
【従来の技術】
従来のこの種の副水路とリリーフ機能を備えた衛生洗浄装置は特開平３−６６８４４号公報に示すような構成が一般的であった。この装置は図８に示されているように、副水路１は温水タンク２の上流で主水路３から分配され、副流量調節弁４と、その副流量調節弁４の一次側（上流側）の水圧が設定値以上になると開放して便器開口部に通水するリリーフ弁５と、吐水ホース６と、吐水口７とから構成されていた。
【０００３】
【発明が解決しようとする課題】
しかしながら、従来の衛生洗浄装置では、副水路１が温水タンク２の上流で主水路３から分配されているため、温水タンク２と並列して吐水ホース６が必要となり、また、副水路調節弁４や主水路流量調節弁８やリリーフ弁５を内蔵した複雑な分配器９も必要となるので、コスト面やスペース面で不利という課題を有していた。
【０００４】
【課題を解決するための手段】
本発明は、上記課題を解決するために、温水タンクから便器開口部内に連通する副水路には、前記温水タンク内圧が設定値以上になると開放して前記便器開口部内に通水するリリーフ機能を備え、前記温水タンク内には前記加熱ヒータを有する部分と前記副水路の入口部付近で一部連通する仕切板を設け、前記入水路の出口部から前記副水路の入口部まで加熱ヒータを経由しないバイパス水路を形成したものである。
【０００６】
【発明の実施の形態】
本発明は、加熱ヒータを有する温水タンクと、前記温水タンクに水を供給するための入水路と、前記温水タンクから湯を出湯するための出湯路と、前記出湯路と連通し局部を洗浄する洗浄ノズルと、前記温水タンクから便器開口部内に連通する副水路と、前記副水路には、前記温水タンク内圧が設定値以上になると開放して前記便器開口部内に通水するリリーフ機能を備え、前記温水タンク内には前記加熱ヒータを有する部分と前記副水路の入口部付近で一部連通する仕切板を設け、前記入水路の出口部から前記副水路の入口部まで加熱ヒータを経由しないバイパス水路を形成したものである。
【０００７】
そして、副水路が簡単な構成になるとともに短くなるため、吐水ホースや流量調節弁を兼ねた分配器などの配管部品が不要となり、コスト面やスペース面で有利である。
【０００８】
また、入水路の出口部から温水タンクに入った水の大部分はバイパス水路を通って副水路の入口部まで行くので、副水路には入水路からの水が加熱されることなく直接通水されることになり、温水タンク内の保温された水は、攪拌されることなく温水タンク内を押し上げられるので、熱効率が高くなる。
【００１１】
さらに、バイパス水路は、温水タンクの高さより一段低い部分の内面に仕切板としてのリブを有する温水タンク上部部材と、温水タンク下部部材を結合することにより、前記温水タンク上部部材の内周と前記温水タンク下部部材の内周と前記リブとにより形成されているものである。
【００１２】
そして、バイパス水路は温水タンクと一体に形成することが可能となり、簡単に製造することができる。
【００１５】
さらに、リリーフ機能を有するリリーフ弁を備えた排水栓を温水タンク下部に取り付けたものである。
【００１６】
さらに、排水栓は、リリーフ弁コマと、前記リリーフ弁コマを温水タンク方向に付勢する弾性体と、前記温水タンク側に入水部を有し前記リリーフ弁コマおよび前記弾性体を内蔵する排水栓ケースと、前記排水栓ケースの便器開口部側には前記排水栓ケースとで吐水部を形成する排水栓フタとを備え、前記温水タンク内圧が設定値以上になると開放して前記便器開口部内に通水するものである。
【００１７】
そして、副水路が温水タンク下部に設けられたリリーフ機能を有した排水栓だけで構成されるため、コスト面やスペース面で有利である。
【００１８】
さらに、排水栓は円筒形状で、温水タンク側に温水タンク下部の穴に水密に取り付けるためのシール部材を、吐水口側に前記排水栓を回転させるためのレバーを有し、回転することにより前記シール部材のシール性を緩和するものである。
【００１９】
そして、排水栓のシール部材はレバーを動かすだけでシール性が緩和されるので、温水タンクなどの排水を容易に行うことができる。
【００２０】
以下、本発明の実施例について図面を参照して説明する。
（実施例１）
図１は本発明の実施例１の衛生洗浄装置の水回路構成図である。
【００２１】
図１において、便器１０の上に衛生洗浄装置本体１１が設置されており、衛生洗浄装置本体１１の内部には、一次側（上流側）より、ストレーナ１２、逆流防止弁１３、水抜栓１４、定流量弁１５、止水電磁弁１６、入水路１７、温水タンク１８が設けられている。そして、温水タンク１８の上部からは、出湯路１９と流量調節兼水路切換弁２０を介して肛門洗浄ノズル２１ａまたはビデ洗浄ノズル２１ｂに連通する主水路２２と、それと並立して温水タンク１８の下部に入口部２３と便器開口部１０ａに吐水部２４を有しリリーフ弁２５と排水栓２６を並立してなる副水路２７が設けられている。また、温水タンク１８内には、加熱ヒータ２８と、入水路１７の出口部２９から副水路２７の入口部２３まで加熱ヒータ２８を経由しないバイパス水路３０が設けられている。
【００２２】
（実施例２）
図２は本発明の実施例２の衛生洗浄装置の温水タンクの斜視図、図３は同温水タンクの副水路部分を含む縦断面図、図４は同温水タンクの入水路部分を含む縦断面図である。
【００２３】
図２において、温水タンク１８の外周の側面部３１と前面部３２は低くなっている。図３と図４において、リブ３３が温水タンク１８の底面１８ａ近くまで突出して設けられることによってバイパス水路３０が形成されている。また入水路１７の出口部２９は側面部３１に設けられ、副水路２７の入口部２３は前面部３２に設けられている。
【００２４】
（実施例３）
図５は本発明の実施例３の衛生洗浄装置の排水栓部分の縦断面図、図６は同排水栓部分の横断面図、図７は同排水栓部分のガイド溝部分の拡大縦断面図である。
【００２５】
図５において、排水栓ケース３４は中間部分に絞り部３４ａを有した２段の円筒状の形状で両端には開口部を有し、内側には絞り部３４ａにリリーフ弁コマ３５がコイルバネのような弾性体３６によって入口部２３方向へ付勢されて取り付けられている。排水栓ケース３４の外側には、温水タンク１８の下部の穴３７との水シールのためのＯリングのようなシール部材３８が取り付けられている。さらに、図６と図７において、排水栓ケース３４の外側には、裏板３９と一体に構成されたガイド溝４０に入る突起部４１と、開口部を塞ぐように排水栓フタ４２が取り付けられている。また、ガイド溝４０は排水栓２６を左右に回転させたとき排水栓２６が前後に移動するように図７に示すような形状になっている。そして、排水栓フタ４２には吐水部２４と排水栓２６を回転させるためのレバー４３が取り付けられている。
【００２６】
【発明の効果】
以上の説明から明らかなのように本発明の衛生洗浄装置によれば、次の効果が得られる。
【００２７】
温水タンクから便器開口部内に連通する副水路に、温水タンク内圧が設定値以上になると開放して便器開口部内に通水するリリーフ機能を設けることにより、副水路を簡単にできるとともに短くできるので、吐水ホースや流量調節弁を兼ねた分配器などの配管部品が不要となり、コスト面やスペース面で有利であるとともに、リリーフ機能により、水道元圧が高いときや、主水路の流量が絞られたときなど温水タンク内圧が高くなると便器開口部に通水されるので、温水タンクの耐圧保護ができる。
【００２８】
また、温水タンク内には加熱ヒータを有する部分と一部連通する仕切板を設け、入水路の出口部から副水路の入口部まで加熱ヒータを経由しないバイパス水路を形成したので、副水路には入水路からの水が加熱されることなく直接通水され、温水タンク内の保温された水は攪拌されることなく温水タンク内を押し上げられ、熱効率を高くできる。
【００２９】
また、バイパス水路は、温水タンクの高さより一段低い部分の内面に仕切板としてのリブを有する温水タンク上部部材と、温水タンク下部部材を結合することにより、温水タンク上部部材の内周と温水タンク下部部材の内周とリブとにより形成されているので、バイパス水路は温水タンクと一体に形成することが可能となり、簡単に製造することができる。
【００３０】
また、副水路は温水タンク下部より連通され、副水路内にはリリーフ機能としてのリリーフ弁と並列に排水栓を備えたものであるので、温水タンクなどの排水を排水栓を開くことによって容易に行うことができるとともに、リリーフ機能の設定値を温水タンクの水頭圧より高く設定していると、止水放置時の温水タンク内の貯湯水の抜けを防止できる。
【００３２】
さらにまた、リリーフ機能を有するリリーフ弁を備えた排水栓を温水タンク下部に取り付けたので、副水路が温水タンク下部に設けられたリリーフ機能を有した排水栓だけで構成され、コスト面やスペース面で有利である。
【００３３】
さらにまた、排水栓は円筒形状で、温水タンク側に温水タンク下部の穴に水密に取り付けるためのシール部材を、吐水口側に前記排水栓を回転させるためのレバーを有し、回転することによりシール部材のシール性を緩和するものであるので、レバーを動かすだけで排水栓のシール部材のシール性が緩和され、温水タンクなどの排水を容易に行うことができる。

The present invention provides a hot water tank having a heater, a water inlet for supplying water to the hot water tank, a hot water outlet for discharging hot water from the hot water tank, and a local part which is in communication with the hot water tank. A washing nozzle, a sub-channel communicating from the hot water tank into the toilet opening, and the sub-channel having a relief function that opens when the hot water tank internal pressure becomes equal to or higher than a set value and allows water to flow through the toilet opening, Provided in the hot water tank is a partition plate that partially communicates with the portion having the heater and near the inlet of the sub-water channel, and a bypass that does not pass through a heater from the outlet of the water inlet to the inlet of the sub-water channel. It formed a channel.
[0007]
Further, since the auxiliary water channel has a simple configuration and becomes short, piping parts such as a water discharge hose and a distributor also serving as a flow control valve become unnecessary, which is advantageous in terms of cost and space.
[0008]
In addition, most of the water that has entered the hot water tank from the outlet of the inlet channel passes through the bypass channel to the inlet of the sub-channel, so that the water from the inlet channel flows directly into the sub-channel without being heated. As a result, the water kept warm in the hot water tank is pushed up in the hot water tank without being stirred, so that the thermal efficiency is increased.

A lever 43 for rotating the spout 24 and the drain plug 26 is attached to the drain plug lid 42.
[0026]
【The invention's effect】
As is clear from the above description, according to the sanitary washing device of the present invention, the following effects can be obtained.
[0027]
By providing a relief function that opens when the internal pressure of the hot water tank exceeds a set value and allows water to flow into the toilet opening, the secondary water channel can be simplified and shortened, because the auxiliary water channel communicating from the hot water tank into the toilet opening is provided. Piping parts such as a water discharge hose and a distributor that also serves as a flow control valve are not required, which is advantageous in terms of cost and space, and the relief function reduces the flow rate of the main water channel when the water source pressure is high or When the internal pressure of the hot water tank becomes high, for example, when water is passed through the toilet opening, the pressure resistance of the hot water tank can be protected.
[0028]
In addition, a partition plate that partially communicates with a portion having a heater is provided in the hot water tank, and a bypass channel that does not pass through a heater from an outlet of an inlet channel to an inlet of a sub-channel is formed. The water from the water inlet is directly passed through without being heated, and the water kept in the hot water tank is pushed up in the hot water tank without being stirred, so that the thermal efficiency can be increased.
[0029]
In addition, the bypass water passage is formed by connecting a hot water tank upper member having a rib as a partition plate to an inner surface of a portion one step lower than the height of the hot water tank, and a hot water tank lower member, so that the inner periphery of the hot water tank upper member and the hot water tank are connected. Since the lower channel is formed by the inner periphery of the lower member and the ribs, the bypass water passage can be formed integrally with the hot water tank, and can be easily manufactured.
[0030]
The sub-canal is connected from the lower part of the hot water tank, and the sub-canal is equipped with a drain valve in parallel with the relief valve as a relief function. When the set value of the relief function is set to be higher than the head pressure of the hot water tank, it is possible to prevent the hot water from flowing out of the hot water tank when the water is stopped.
[0032]
Furthermore, since a drain tap equipped with a relief valve having a relief function is attached to the lower part of the hot water tank, the sub-channel is constituted only by a drain tap having a relief function provided at the lower part of the hot water tank, which reduces cost and space. Is advantageous.
[0033]
Furthermore, the drain cock has a cylindrical shape, a seal member for watertightly attaching to a hole at the lower part of the hot water tank on the hot water tank side, and a lever for rotating the drain cock on the water outlet side, and by rotating, Since the sealing property of the sealing member is relaxed, the sealing property of the sealing member of the drain plug is relaxed only by moving the lever, and the drainage of the hot water tank or the like can be easily performed.
